Great. My car only has 600 miles on it, was thinking of putting the stock 215/45/18s and TPMS on 18x8 RX-8 wheels. I know that's stretching it a bit, but I should be alright for street use, agreed?
Your choice... But I wouldn't recommend it... I'd just ride on the stock rims/wheels until they are done for safety's sake...
The OEM 215-45-18 tires will work fine on the 18x8 wheel. There just is not much protection for the rim against curb rash. I and many many other members are running the OEM tire. We all are doing the same thing, waiting to wear the OEM tires out to go wider.
I would not recommend that... That is way too narrow for an 8" wheel!!!!!
Minimum on a 8.0" wheel should be 235/40 or 225/45!!!
I have stok tires on 8" rims and they are working fine.....people are streching 195 on 9" wide rims and never heared that tire fall off
People drive without seat belts, drive with under-inflated tires, with bald corded tires, etc...etc...etc...
The point is it doesn't make it right and safe...
195mm tire on a 9" rim is utterly asinine... In addition to looking ghetto...
If you can't afford the correct sized tire for your rims, then don't buy rims.
Tires have specs for a reason.
Some people choose not to follow them...their choice.
